Crater Design Experiment Aim: To see how the height in which the ball is dropped from affects the depth of the crater. Hypothesis: I predict that as the height in which the ball is dropped from increases‚ so does the depth of the crater (the data will be directly proportional). The scientific knowledge which supports this is that the golf ball has a gravitational potential energy which increases as the ball is dropped from higher heights. When the height increases the ball gains more gravitational

ending at the head of B—so that it completes the triangle. If A‚ B‚ and C are vectors‚ it must be possible to perform the same operation and achieve the same result (C) in reverse order‚ B + A = C. Quantities such as displacement and velocity have this property (commutative law)‚ but there are quantities (e.g.‚ finite rotations in space) that do not and therefore are not vectors. The other rules of vector manipulation are subtraction‚ multiplication by a scalar‚ scalar multiplication (also known

African American men were lied to and left to die while under the care of doctors and scientist thinking that they were being taken care of. The men participated in an experiment called the Tuskegee syphilis Experiment were the men would partake in a medical study. This paper will examine how scientist took advantage of the men who participated in this experiment and neglected to tell them the truth. This topic really interest me because it took 40 years into the experiment to see that it was not

Silver Mirror Experiment Background: This experiment was first conducted by Bernhard Tollens‚ it is used to determine whether a carbonyl containing compound is an aldehyde or a ketone. An aldehyde is a compound containing a formyl group (CHO).The experiment involves diamminesilver complex and a chemical reagent (also known as “Tollens’ reagent”) which in this case is glucose. In a successful experiment a reflective silver metal should precipitate‚ with characteristics identical to that of a mirror’

PLAN OF INVESTIGATION Fundamental Science Salt water egg experiment Result Some objects float on top of the ocean‚ and other objects sink to the bottom. Why? In this salt water egg experiment we can find a solution for this question. It was noted that to make the egg float salt is needed to dissolve into fresh water. When the egg was lowered into the fresh water container it started to sink. But when salt was added to the container the egg started to float. Adding salt

United States. The people who wanted the war were mostly Democrats and Southerners. Southerners supported the war because they were in hope that more land would be acquired meaning more states would be admitted into the union as slave states. For this same reason the Whig Party opposed the war because they were abolitionists. Abolitionists opposed slavery so with the addition of new slave states‚ their hopes of making the U.S a slave free country were thwarted. Abolitionists such as Members from

Eating Chocolate Helps Students Become Happier Henry Vuong Dennis Lin Stella Zhang Introduction: Our experiment is based on a former experiment described in the article A Scientific Experiment‚ In Search of Chocolate Happiness. It was an experiment in a mall Cafe called Butler Chocolate‚ with a purpose of finding a way to help shoppers become happier. By giving each customer a piece of Butler ’s chocolate‚ the Cafe hoped to increase the number of smiling faces at the mall. Early findings

Sulfa Drugs: Preparation of Sulfanilamide Introduction The purpose of this experiment is to prepare sulfanilamide from p-Acetamidobenzenesulfonyl chloride. This will be done using reflux‚ vacuum filtration‚ and melting point determination. Experiment Scheme6 Figure 1. Reaction equation.6 A hot water bath was prepared in a fume hood using a 250-mL beaker. 2.5 g of p-acetamidobenzenesulfonyl chloride was placed into a 50 mL Erlenmeyer flask and 11 mL of dilute ammonium hydroxide solution
